0301.94.01.00 - Atlantic and Pacific bluefin tunas (Thunnus thynnus, Thunnus orientalis)

This HTS category specifically classifies live Atlantic and Pacific bluefin tunas, scientifically identified as *Thunnus thynnus* and *Thunnus orientalis*. These are large, migratory fish renowned for their culinary value and are typically distinguished by their powerful build and the characteristic blue coloration of their undersides. This classification applies to specimens intended for aquaculture, restocking, or other live trade purposes, rather than those intended for immediate processing.

It is crucial to differentiate this classification from its siblings. While all fall under "Other live fish," this code is exclusively for the Atlantic and Pacific varieties of bluefin. For instance, HTS code 0301.95.00.00 covers Southern Bluefin tuna (*Thunnus maccoyii*), a distinct species. Other sibling categories, such as those for trout, eels, or carp, are clearly defined by their respective species and families, highlighting the specificity required within this chapter of the Harmonized Tariff Schedule.

As this is a leaf node within the HTS structure, there are no further subdivisions under 0301.94.01.00. Therefore, classification relies solely on the accurate identification of the species as either Atlantic or Pacific bluefin tuna. The primary distinguishing factor for this specific code is the species identification, ensuring that live specimens of these particular bluefin tunas are correctly categorized for international trade.
